In this paper we describe Quorum, a non-invasive approach to scalable quality-of-service provisioning that uses traffic shaping, admission control, and response monitoring at the border of an Internet site to ensure throughput and response time guarantees.
We experimentally compare an implementation of Quorum both to hardware over-provisioning and to leading software approaches using real world workloads. Our results show that Quorum can enforce the same QoS guarantees as either of the… CONTINUE READING
